摘要 |
A contact fixing device primarily used in electrophotographic copiers is described. It has a driven and heated fixing surface which is made from a partially resilient material and a driven pressure surface which presses against the fixing surface forming a fixing zone through which copy material can be fed for fixing a toner image thereon. It also has a hollow perforated cleaning roller which while rotating in contact with the fixing surface takes up toner from the fixing surface. To prevent contamination of the device due to toner material flowing over the ends of the cleaning roller, this roller is provided with a narrow circular thickening near each end.
